/**
 * Runs the repo's independent audits concurrently.
 *
 * Each audit is a self-contained read-only pass over the tree, so running them as 20-odd
 * sequential CI steps spent most of its wall clock waiting on single-threaded file walks.
 *
 * The list is derived from the `check:*` scripts in package.json rather than restated here,
 * so a new audit is picked up by default and has to be opted *out* deliberately. The previous
 * hand-maintained list had already drifted: `check:cron-parity` existed, passed, and ran
 * nowhere. Audits that need a git base ref or write files stay excluded and keep their own
 * workflow step.
